Specification of Letters Patent.

Patented A11 12,1913.

Application filed June 5, 1912. Serial No. 701,886.

T 0 all whom it may concern:

Be it known that I, HERBERT E. Manor, citizen of the United States, residing at Mount Vernon, in the county of lVestchester and State of New York, have invented certain new and useful Improvements in Faucet-Couplings, of which the following is a specification.

The object of this invention is to provide a simple and inexpensive device which may be readily fitted upon the end of an ordinary faucet for the purpose of coupling to the same a water conveyer, hydraulic motor, or other device.

The invention seeks to provide a coupling which may be readily fitted upon faucets of various diameters and-which will form a water-tight oint therewith.

These stated objects, and such other incidental objects as will hereinafter appear, are attained in such a device as is illustrated in the accompanying drawings, and the invention consists in certain novel features of the same, which will be hereinafter first fully described and then more particularly pointed out in the appended claims.

In the drawings :Figure 1 is a longitudinal section of my improved coupling showing the same fitted upon the end of a faucet and showing a portion of a vacuum massage device connected therewith; Figs. 2 and 3 are sectional views showing difl'erent forms of caps; Figs. 4 and 5 are sectional views showing different forms of coupling bodies.

My device consists, essentially, of a coupling body 1 and a cap 2, which have a threaded connection and are preferably stamped out of sheet metal. In the form shown in Fig. 1, the body portion of the coupling is constructed with a tubular extremity in which are formed spiral corrugations, as shown at 3, whereby it may be screwed into the ring or collar, 4, at the upper end of the massage apparatus or other device. Rising from this lower tubular portion is a neck 5 which is contracted upwardly and terminates in a radial annular shoulder 6 adapted to support a gasket or elastic ring 7. Extending upwardly from the outer edge of the annular shoulder 6 is a rim or annular flange 8 which is formed with spiral corrugations, as shown, whereby it may enter the cap 2 and have a threaded engagement with the same. The cap is substantially a sleeve having its lower end slightly flared, as shown at 9, to facilitate the entrance of the flange 8 into the same and having its upper end doubled inwardly on itself, as shown at 10, and then reversed and carried upwardly to form a conical coinpressing lip 11. The main portion of the cap is formed with spiral corrugations which will engage the spiral corrugations in the flange or rim 8, and the inverted portion 10 of the cap is spaced from the outer main body of the same to provide a clearance space, so that the coupling body may enter the cap to whatever extent is necessary under any conditions. The upper end of the elastic collar 7 is beveled inwardly, as shown at 12, to facilitate the engagement of the same over the end of the faucet.

The application of the device, it is thought, will be readily understood. The coupling body 1 is engaged in the upper end of the massage apparatus or other device to be coupled to the faucet and the cap 2 is then screwed down over the body, the elastic collar or gasket 7 having been first placed within the body upon the annular radial shoulder 6 of the same. The device is then pushed upwardly over the end of the faucet so that the gasket will fit around the same, and the cap is then turned downwardly upon the body coupling, so that the conical or inclined compressing lip 11 will engage the gasket 7 and compress the upper end of the same around the faucet so that a water-tight joint will be formed therewith. To further guard against leakage, a washer 13 may be placed within the upper end of the massage apparatus or other device to fit against the lower end of the coupling body, and I have illustrated such a washer in Fig. 1.

The construction illustrated in Fig. 1 and specifically described is that preferred by me, but the invention is not limited in its scope to this exact form.

In Fig. 2, I have shown a form of cap in which the end of the sleeve, from which the cap is constructed, is not doubled completely on itself, as shown at 10 in Fig. 1, but is carried radially inward, as shown at 14, and the extremity of the same is then bent to ward the opposite end of the sleeve and flared to form the compressing surface 15. The operation of this cap will be the same in all respect-s as that shown in Fig. 1 and previously described.

In Fig. 3 is shown a cap in which the end of the sleeve, from which the cap is constructed, is doubled inwardly on itself in the same manner as the cap shown in Fig. 1, but the inner extremity of the doubled over portion is disposed radially within the cap, as shown at 16, instead of being inclined, as shown in Figs. 1 and 2.

In Fig. 4, I have shown the body portion of the coupling as having its neck 17 flared upwardly instead of being contracted upwardly, as shown in Fig. 1, so that a very slight annular shoulder 18 is provided at the upper end of the flared portion, and, in Fig. 5, I have shown the coupling body as extending cylindrically from its lower extremity to the annular radial shoulder 19 and the washer 2O placed upon the said shoulder.

The caps and bodies may be used interchangeably, so that any particular conditions may be met, except that the cap shown in Fig. 8 can only be used in connection with the body, shown in Fig. 4, as otherwise the gasket will not be properly com pressed around the end of the faucet.

It will be readily seen that I have provided a coupling which is exceedingly simple in its construction and which may be readily fitted to any faucet, and in which the members may be easily separated for the purpose of repairing, cleaning, or renewing the same.

It will be noted that in all forms of the device a clearance space is provided between the compressing lip and the outer wall of the cap to receive the rim of the body member, so that the gasket is spaced from the said rim and will not be worn by the threads or corrugations and will not interfere with the movement of the said memher, the body member and the cap being relatively movable throughout the full extent of the rim of the cap.

That I claim is 1. A device for the purpose set forth comprising a sheet metal body member having a lower tubular portion, an annular radial shoulder above said tubular portion and an annular rim rising from the outer edge of said shoulder, a cap threaded upon said rim and having its upper portion doubled in-- wardly on itself to provide an annular chamber receiving the rim of the body member and extending upwardly from said annular chamber to form an inclined annular compressing lip, and a gasket seated upon the annular shoulder of the body member and held by and between the said shoulder and said compressing lip.

2. An attachment for faucets comprising a tubular body member having an annular shoulder and an annular rim rising from said shoulder, a tubular cap threaded on the rim of the body member and having its upper portion bent inwardly to provide an annular lip spaced from the body of the cap to be encircled by the rim of the body mem ber, and a gasket held by and between the said annular shoulder and the said annular lip to be forced by the same against the faucet.

3. An attachment for faucets comprising inter-engaging coupling members mounted to have relative axial movement, and a single integral elastic ring arranged within the coupling members to fit closely around the end of the faucet, one of the coupling members having an annular radial shoulder fitting against one end of said ring and the other coupling member having an annular shoulder disposed at an angle to its radius and fitting against the opposite end of the ring whereby the axial movement of the members may cause said shoulders to approach and compress the ring between themselves and around and against the faucet.

In testimony whereof I aflix my signature in presence of two witnesses.
